Description

[Technical field]

[0001] The present invention relates to a paper container having a lid that is detachable from a container body. [Background technology]

[0002] Many paper containers are provided with a lid that is continuous with the side of the container body, or with lids that are formed by butting together two continuous parts of two opposing sides. A lid provided on the container body has the advantage that it is easy to identify the position of the lid relative to the container body and that the lid will not get lost, but when removing contents from the container body, the lid often tries to close, obstructing removal of the contents. As such, paper containers with a lid that is integrated with the container body are inconvenient for removing contents, so a paper container with a lid that can be attached and detached from the container body has been proposed (Patent Document 1).

[0003] Patent Document 1 discloses a paper container (carry carton) in which a lid (top cover) with a handle (handle plate) is placed over a container body (box) with an open top, and the connecting piece (fastening piece) of the handle of the lid is inserted into a connecting slit (fastening hole) of the connecting plate (handle fastening plate) of the container body, and an insert piece of the outer periphery of the lid (side cover plate) is inserted into a latch slit (notch) of the side plate of the container body to close the lid (Patent Document 1, [Claim 1]). The paper container disclosed in Patent Document 1 makes it easy to put in and take out contents (snacks, etc.) by removing the lid from the container body, and improves the appearance of the container body with the lid removed (Patent Document 1,

[0012] ). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Document 1: Japanese Patent Application Laid-Open No. 2001-322626 Summary of the Invention [Problem to be solved by the invention]

[0005] The paper container disclosed in Patent Document 1 has a handle on the lid. For this reason, the container body with the lid removed can only be carried by, for example, holding it with a hand on the bottom. This does not seem to assume that the contents will be removed from the container body and transferred to another container, and then the container body will be carried. However, it would be convenient if the container body could be moved with the contents still inside and the contents could be taken out directly from the container body. However, the paper container disclosed in Patent Document 1 is not suitable for such use. Therefore, in a paper container with a lid that can be attached and detached to the container body, a study was conducted to provide a handle on the container body so as not to interfere with the attachment and detachment of the lid to and from the container body. [Means for solving the problem]

[0006] As a result of these studies, we have developed a paper container with a lid that can be attached and detached to the container body, in which the lid has a pair of upward-facing key pieces protruding from point-symmetric positions on the lid's plane where the lid handle is provided, and the container body has a pair of body handles that hang along the upper edge surrounding the open top surface at the same point-symmetric positions as the lid's key pieces, and with the open top surface covered, each of the key pieces of the lid attached to the container body is engaged from below with the inner edge of the opening of the body handle.

[0007] The paper container of the present invention is configured with a detachable lid on the container body, and has a lid-side handle on the lid and a body-side handle on the upper edge of the opened container body, so that the container body can be carried by holding the lid-side handle. Here, the body-side handle hooks the key piece of the lid from below onto the inner periphery of the opening, eliminating the need to provide a separate hooking portion for the key piece. The body-side handle "hangs along the upper edge surrounding the open top surface" means that both ends of the body-side handle that spans the opening are connected to the same upper edge, and the entirety is contained on the same upper edge. As a result, the body-side handle is formed as a surface material that is continuous with the side surface.

[0008] The container body can have an opening by hollowing out the inside of the body-side handle. However, it is preferable to provide a hollowing piece connected to the upper edge of the container body on the body-side handle so as to leave a hollowed-out portion, and to form the opening in the body-side handle by bending the hollowing piece while connected to the upper edge. When attaching a lid to the container body, the hollowing piece is folded toward the open top surface of the container body, and supports the lid attached to the container body from below while closing the open top surface. Furthermore, when removing the contents from the container body with the lid removed, the hollowing piece can be flipped up and placed in the opening of the body-side handle so as not to get in the way.

[0009] When the lid is configured such that the outer peripheral surface lowered from the outer peripheral edge of the lid plane that is equal to the top surface of the opened container body has two intersecting portions, deformation of the lid plane is suppressed, and in particular, the descent of the key piece due to sinking of the lid is prevented, making it difficult for the key piece to come off the handle on the main body side. When the top surface of the container body is rectangular in plan view, the outer peripheral surface "has two intersecting portions" is the outer peripheral surface in two directions along each of the upper edges of the four sides surrounding the top surface. In this case, the outer peripheral surfaces along each side intersect at the corners. In addition, when the top surface of the container body is elliptical in plan view, the outer peripheral surface "has two intersecting portions" is the outer peripheral surface that extends in an elliptical shape along the upper edge surrounding the top surface, and corresponds to the two-way portion where the continuously curved outer peripheral surface intersects. Effect of the Invention

[0010] The present invention provides a paper container that is easy to use, since the container body with the lid removed and the top surface widely open can be carried using the handle on the body side, allowing the container body to be carried with the contents stored therein and the contents to be removed from the container body at the destination. This effect is due to the fact that the handle on the body side of the container body serves as a means for making the container body easier to carry and also as a hooking part for the key piece of the lid. Since the container body does not need to have a hooking part for the key piece other than the handle, protrusions on the handle that would interfere with removing the contents can be kept to a minimum, and the appearance is not marred.

[0011] The hollowed-out piece that forms the opening of the outer handle is bent toward the open top surface of the container body, thereby supporting the lid attached to the container body from below while covering the open top surface, and preventing the key piece from coming off the body-side handle due to the lid sinking. Also, the lid has an outer peripheral surface with two intersecting portions, which suppresses deformation of the lid plane and prevents the key piece from coming off the body-side handle due to the lid sinking. In this way, the present invention firmly attaches the lid to the container body and prevents the lid from coming off accidentally. [Brief description of the drawings]

[0013] Hereinafter, the embodiment of the present invention will be described with reference to the drawings. As shown in Figs. 1 to 3, the paper container of the present invention is composed of a lid 1 that is square in plan view and symmetrical from front to back and left to right, and a container body 2 that is also square in plan view and symmetrical from front to back and left to right. The lid 1 and the container body 2 may have different shapes in plan view, as long as the lid 1 can be attached so as to cover the open top surface 21 of the container body 2 (see the wavy frame in Fig. 1). In addition, the container body 2 in this example has a relatively shallow configuration, but the present invention can also be applied to a paper container with a deep container body 2.

[0014] As shown in Figs. 1 to 7, the lid 1 is made of a single blank 16, which forms the lid plane 13, the lid handle 11, and the outer peripheral surfaces 14, 15. The lid handle 11 is formed by folding the upper and lower central parts of the blank 16 in a mountain shape to separate the lid plane 13 into front and rear parts, and then stacking two blanks. The lid plane 13 has an outer peripheral surface 14 that is continuous with the entire side and extends vertically from a side parallel to the extension direction of the lid handle 11. The lid plane 13 has an outer peripheral surface 15 that is divided on both sides and extends vertically from a side of the lid plane 13 that is perpendicular to the extension direction of the lid handle 11. The outer peripheral surface 15 is maintained in an intersecting state with the outer peripheral surface 14 by attaching the adhesive margins 141 at both ends of the outer peripheral surface 14 from the inside.

[0015] The lid handle 11 has an opening 111 for inserting a hand by overlapping a thin and elongated hollowed-out piece 112 flush with the lid flat surface 13. The key piece 12 is formed integrally with the lid handle 11 at the front and rear ends of the lid handle 11, which are point-symmetrical. The key piece 12 may be formed separately from the lid handle 11. The outer peripheral surface 15 of this example has a crease 151 for folding the outer peripheral surface 14 so that it overlaps. As a result, when the lid flat surface 13 is folded to sandwich the lid handle 11, and then the outer peripheral surface 15 is folded so that the outer peripheral surface 14 overlaps the lid flat surface 13, the entire lid 2 can be folded and stacked, reducing the space required for storage.

[0016] As seen in Figures 1 to 3 and 8 to 11, the container body 2 has the bottom 23, side surfaces 22, and body-side handle 24 formed from a single blank 25. The side surfaces 22 are horizontally long trapezoids with the four sides of the bottom surface 23, which is a square in plan view, as its upper sides. As a result, the container body 2 has the adhesive margins 223 at both ends of the side surfaces 22 with the body-side handle 24 provided on the inside of the side surfaces 22 without the body-side handle 24. In the folded position When attached, it is formed into an inverted frustum shape with the top surface 21 being wider than the bottom surface 23. The open top surface 21 is the portion surrounded by the upper edge 221 of the side surface 22 (see the wavy frame in Figs. 1 and 8).

[0017] The body-side handle 24 is a roughly semicircular piece of paper that protrudes from the upper edge 221 of the side surface 22, and is formed by punching out a roughly semicircular cut-out piece 242 provided on the inside, to form an opening 241 of the same shape as the cut-out piece 242. The body-side handle 24 is located in a point-symmetrical position with the apex position of the opening 241 aligned with the left-right middle position of the side surface 22, and both ends are connected to the side surface 22 via a fold 222 that continues to the upper edge 211. The container body 2 in this example is intended to be used as formed, but it is also possible to fit a paper or resin inner container of the same size as the container body 2 into it, or to store multiple paper or resin inner containers smaller than the container body 2 side by side.

[0018] The paper container of the present invention can be carried with the container body 2 with the lid 1 removed by holding the body-side handle 24. As shown in Figures 1 and 8, the container body 2 is carried with the body-side handle 24 held in the hand with the cut-out piece 242 that forms the opening 241 of the body-side handle 24 folded toward the top surface 21 at the crease 222 that continues to the upper edge 211, so that the cut-out piece 242 prevents the hand from touching the contents. When the container body 2 has been carried, the cut-out piece 242 can be raised and fitted into the opening 241 of the body-side handle 24 so that it does not get in the way of removing the contents.

[0019] The procedure for attaching the lid 1 to the container body 2 of the paper container of this example will be described. When attaching the lid 1 to the container body 2, as shown in Figs. 12 to 14, the position of the key piece 12 of the lid 1 is aligned with the position of the body-side handle 24 of the container body 2, and the lid 1 is lowered to cover the top surface 21 of the container body 2. At this time, the lid 1 can be placed on the container body 2 with the body-side handle 24 protruding from between the outer peripheral surface 15 divided into left and right. In other words, the positional relationship between the lid 1 and the container body 2, in which the body-side handle 24 protrudes from between the outer peripheral surface 15, is such that the key piece 12 of the lid 1 and the body-side handle 24 of the container body 2 are aligned at the same time.

[0020] In the present embodiment, the lid surface 13 of the lid 1 and the open top surface 21 of the container body 2 are substantially the same shape, and the periphery of the lid surface 13 of the lid 1 coincides with the upper edge 221 of the side surface 22 of the lid 2. The continuous outer peripheral surface 14 of the lid 1 completely closes the gap between the lid surface 13 and the upper edge 221 of the side surface 22 of the container body 2. The divided outer peripheral surface 15 of the lid 1 partially closes the gap between the lid surface 13 and the upper edge 221 of the side surface 22 of the container body 2. The part of the gap between the lid surface 13 and the upper edge 221 of the side surface 22 of the container body 2 where the outer peripheral surface 15 is not present is closed by the body-side handle 24 of the container body 2. In this way, the top surface 21 of the container body 2 to which the lid 1 is attached is closed in a sealed state.

[0021] As shown in Figs. 15 to 19, after the attachment of the lid 1 to the container body 2, the body-side handle 24 of the container body 2 is tilted toward the key piece 12 of the lid 1, and the key piece 12 is engaged from below with the inner peripheral edge of the opening 241 of the body-side handle 24, completing the fixing of the lid 1 to the container body 2. The body-side handle 24 is folded along the crease 222, which is the boundary with the side surface 22 of the container body 2, and tilted toward the key piece 12 of the lid 1. However, the body-side handle 24 tries to stand up so as to align with the side surface 22. As a result, the key piece 12 of the lid 1 is firmly engaged with the inner peripheral edge of the opening 241 of the body-side handle 24, and the lid 1 and the container body 2 are integrated.

[0022] The outer peripheral surfaces 14, 15 of the lid 1 are each perpendicular to the lid flat surface 13 and perpendicular to each other in two directions, so deformation of the lid flat surface 13 is suppressed. Furthermore, in the paper container of this example, when the cutout piece 242 forming the opening 241 of the body side handle 24 is folded toward the upper surface 21 at the crease 222 continuing to the upper edge 211, the cutout piece 242 tries to stand up so as to align with the side surface 22, and supports the lid flat surface 13 of the lid 1 attached to the container body 2 from below. This prevents the key piece 12 from descending due to the sinking of the lid 1, making it difficult for the key piece 12 to come off the body side handle 23. In this way, the container body 2 to which the lid 1 is attached can be stably carried by holding the lid side handle 11. [Explanation of symbols]
